T aZZ wl om zlt may concern:

Be it known that I, FREDERIC W. HILLARD,

a resident of Tottenville, in the county of Richmond and city and Statcof New York, have invented certain new and useful Improvements in Type-lVriting Machines, of

which the following is a specification.-

This application, which is a division of my former application, tiled in the United States Patent Ofiice on the 25th day of May, 1897,

.and serially numbered 638,007, allowed September 3, 189$,and renewed July 31,1900, as.

'Serial No. 25,45l, relates to certain improvementsin type-shifting mechanism for printing any one of a plurality of characters carbar, this arrangement of type being especially applicable to machines adapted to Write on fiat surfaces-such, for instance, as machines now known in the art as book type-writers.

The several novel features which I claim in this application will be hereinafter more fully described and claimed. i

Referring to the accompanying drawings, in which like parts are designated bysimilar marks of reference, Figure 1 is a transverse 0 vertical section of a type-writing machine,

showing so much thereof as is necessary to. illustrate my present invention, the section being taken from front to rear. Fig. 2 is a perspective view of a type-head. Fig. 3 is 5 a perspective view of a type-bar. Fig. 4 is a perspective view of the tripping member. Fig. 5 is a perspective view of a type-bar and the parts carried thereon constructed in accordance with my present invention. Fig. 6 is a View similar to Fig. 1, but showing another form of type-shifting mechanism. Fig; 7 is a detail plan view of the bracket-basket of a machine such as that shown in Fig. 6. Fig. Sis a perspective view of the type-bar usedin the machine shown in Fig. 6 with the parts carried thereon and showing in dotted lines the tripping-bracket. Fig. 9 is the trip ping member.

Referring to Figs. 1 and 6, the carriage A their normal position being substantially verthat it can be rocked from one printing position to another printing position. The typebar is broadened and flattened at the end to aiford asuitable mounting for the type-head. The type-head is flat, and the type project therefrom, being substantially radial "to its pivotal point. A screw Cjoins the type-head and type-bar. Its shank passes through the tripping member F of the type-head and the Hat end of the type-bar, and its threaded end is screwed into the type-head. The type-head has a certain range of movement about the axis of the screw by which it is attached to the head of the type-bar. This range of movement is limited by two banking-faces m n, which engage the banking-stops m n on the front and rear of the shank If of the. type-bar T when the type-head is movedthe desired distance to bring one or the other of c the two type thereon into proper position for printing. On the edge of the type-head are two inclined surfaces 't'j, which meet and form an apex. A flat spring Sis attached to the type-bar and extends along its length.- At 5 the end of the spring are two inclined surfaces 19 q, meeting at an apex. This apex and the apex on the type-head areso positioned relatively to each other that the latter will pass the former when the type-head is shifted from one printing position to the other. Whenever the type-head is moved far enough either way to bring the apex between i and j past the apex formed at the end of the spring, the pressure of the spring will be transferred from one of the inclined surfaces on the typehead to the other and the type-head will be forced around the balance of the distance until one of the banking-faces on the type-head engages wit-h the corresponding banking-stop on the shank of thc type-bar, the type-head being held'in its shifted position by the spring S until moved to another position.

Referring now to Figs. 1 to 5, the type-head is provided with a tripping member F, which, as before stated, is pivoted on the screw 0. There is an apertureftherein to receive a pin h, projecting from the side of the typehead, whereby the said parts are caused to move together and which at the same time permits them to be readily disconnected. The tripping member has two oppositely-extending arms, the upper arm projecting beyond the endof the type-bar'and type-head mounted thereon and the' lower arm projecting downwardly along the side of the shank t of type-bar and provided at its lower end with a finger contactingwith the front face of the shank, thus limiting the movement of the tripping member in one direction.

The type-head and its tripping member are shifted from one printing position to the other by means of a tripper, consisting of two parts D and E, the part D consisting of a disk carried on the lower end of a rod d, vertically movable to the frame B concentric with and above the pivotal points of the type-bars. The rod and disk may be depressed by means of a lever d and shift d The said disk is normally hold by the spring d out of the path 7 of the type-bars and type-heads and tripping members carried thereon, but is depressed by the shift-key d to bring it into the path of the tripping member upon the type-bars. The tripper part E consists of a basketor buffer-ring concentric with the ring in which the type-bars. are hungand so located as tion shown upon the front type-bar in Fig. 1,

a type-head moving from its normal position in the basket to the printing-point Will not be shifted, and thus a lower-case character will be printed. If, however, the shift-key be depressed prior to or simultaneous with asses? the depression of a type-key, the disk D will be brought into the path of the tripping member upon the type-head upon the descending type-bar and the upper end of the tripping member will contact with the edge of the disk, being thrown rearwardly on the pivot-screw O and through its attachment by the pin 71 and perforation f to the type-head throwing the latter rearwardly on its pivot to a position (see rear typc-barin Fig. l) to print an uppercase character when brought against the paper. This movement of the tripping member by the disk throws the, former into such position that it clears the edge of the latter, as shown in dotted lines at the rear of Fig. 1, and thus if the disk be held depressed during the return ofthe type-bar to normal position the tripping member will clear the disk and will when the type-bar is completing its return movement contact with the buffer-ring E, whereby its upper end will be thrown forwardly in respect to the type-bar and in a direction opposite to that in which it was tripped by the disk D, thus returning the type-head to the position shown on the front type-bar of Fig. 1, which corresponds to lowercase printing.

It will be noted that by the construction above specified the type-heads when the type: bars arein their normal position are similarly disposed thereon and that if the tripping member D is not depressed the type-bars may move to the printing-point and return without causing relative movement of the typeheads carried thereon, and for the purpose of avoiding unnecessary wear and strain in tripping the type-heads the normal position of the type-heads upon the type-bars should correspond to that seriesof characters thereon which are the most often used'i. e., the lower-case characters. By so disposing the type a type-head is only shifted when it is desired to use an upper-case character, and in such'eventthe type-head is shifted from its normal position on the printing stroke of its type-bar by the disk member D and is reshifted to its normal position bythe basket member E during or upon the completion of the return movement of the type-bar.

To insure the return of the type-head to normal position by the basket member, it is desirable to bring the type-bars back to their normal position with a spring and to cause the basket to act as a stop for such return movement of the type-bars. The finger 9 upon the tripping member F by, contacting with the shank of the bar takes the blow and strain caused by the pressure of the tripping member against the basket, all of which would otherwise be transferred through the banking faces and stops m and m. As the banking-stops define the position of the type-head in printing, it will be obvious thatit is ofimportance to prevent wear thereof,which would impair the alinement, dtc. Thus in addition to the faces and stops for defining the position of thetype-head I have additional faces cease? 'and stops in the form of the finger g and the bar against which it abuts for'takingup the jar produced ontripping the head.

In order to provide for a slight motion of the type-head and tripping member in relation to each other, I form the aperture f of slightly-greater diameter than the diameter of the pin it, which en gages therein, whereby a motion of the tripping member is permitted after the faces and banking-stops m and m or n and n on the type-bar and type-head have been brought into contact, thus relieving the stops of any strain that might be cccasioned by a movement of the tripping member after the type-head had been fully thrown from one printing position'to another, i

In Figs. 6 to 9 I have shown a somewhat dilferent arrangement of the parts. In these figures a ring D is located below and concentric with the buffer and around the type-bars when they are in their normal position, the ring being mounted for vertical movement and hung by the bail d from the rod d, by which it may be raised and lowered. The disk D of Fig.1 is dispensed with, and a series of inwardly-projecting brackets D with hooks d on each side of their inner ends, are

. supported fromthe ring D, each bracket projecting between the shanks of two adjacent type-bars and being when the ring is in its lowered position out of the path of the tripping members upon the type-bars. The ad jacent type-bars are made right and left to permit the engagement of the tripping mem-f bers thereon by the hooked ends d of thein-i termediate bracket-that is to say, the tripping member F of one bar is located to the right thereof and the tripping member of an adjacent bar on the leftthereof, the type-bars beingthus arranged in groups of two,as shown in Fig. '7. The tripping member F has no upper extension, but instead has an ear g upon the rear side of its lower end, the ear projecting rearwardly to behind the spring S upon the typebar, where it is bent across behind the bar in thefo-rm of a finger 9 In the normal position ofthe parts the ear g-con tacts with the basket-ring and the type is in itsnormal position, which is the position of the type-head upon the bar at the front of the machine in Fig. 6, that position correspond ing to lower-case printing. If the shift-key d is not actuated, the type-heads upon the several bars may be'moved to and from the printing-point withoutshi fting the type-head; but should the shift-key be depressed the bracketring will be raised, bringing the hooked ends of the brackets D into position to engage the fingers g on the type-bars as the latter move to printing position, and thus throw the type-head to the position shown upon the rear bar of Fig. 6. During the return of the type-bar to normal position the finger g contacts With the butter-basket and throws the type-head back to normal position, the tripping member F being forced against the banking-pin c on the shank of the typeof contact being above the pivot and in the latter below it. To provide for the printing of the more-used characters in the normal position of the type-head, it is therefore necessary to reverse the arrangement of the upper and lower case characters thereon; but it will be noted that the same general arrangement is preserved in both constructions-that is to say, the IOWGPCftSG character is located between the upper-case character andthe point moving where the contact occurs by which the type-head is thrown.

It will be noted that my tripping mechanism in each of the forms of invention herein shown comprises a movable member for shifting the type-headfrom one printing position to another printing position during the printing stroke of a type-bar, such part being the disk (shown in Fig. 1) orthebracketring D, (shown in Fig. 6,) and a part for reshifting the type-head during the return of the typebar to normal position, this part being the basket-ring. In the embodiment of my invention shown this basket-ring is fixed in the frame of the machine; but this is not necessary, it only being requisite that at all times it be in a position to reshift the type-head during the return stroke of the type-bar, and thus I term the trippcr formed by the basket,- ring a fixed buffer to distinguish it from a part which moves into and out of position for shifting the type-head. In a similar manner I have shown the tripper as beinga separate and independent piece from the type-head; but as itpartakes of the general movement of the type-head in both directions it is obvious that it may be regardedas a part of the type-head.

It will be noted that the type -'head is shifted from its normal position upon the printing stroke of a key and is reshifted to its normal position during the return of the type-bar to normal position, and I will in the claims use the term shifted and reshifted as designating this movement of the type-head from and to normal position.

In the renewal of my original application above named, which application is held in the United States Patent Ofiice in view of a reshift it with a limited relative movement between the said parts, means contacting with the tripping member to shift and reshift it on the type-bar during the printing and return stroke of the type-bar, the trip- IIO ping member having a banking-stop contacting with the type-bar and limiting its move ment, and a series of brackets between the type-bars, each provided with projecting parts for tripping the type-heads of the adjoining type-bars, and I do not, therefore, in this application make any claim thereon, as such matter is claimed in my said renewal application, Serial No. 25,454, of which application this is a division; but
